I dropped my 70-200 last november when I was in puerto rico... well, I didn't drop it. I hadn't properly zipped up my camera bag, and due to it's poor design, when I picked the bag up, my 70-200 slipped out and fell to the floor. It still worked, but the focus ring got really tight. So I continued using it, figuring I could make a decision about having it repaired at a later time. Well, I was forced to make that decision on this day, at Eureka Sand Dunes in DV. I was shooting away with the lens, when I noticed that all the sudden all my shots were over exposing even though the meter was telling me otherwise. I also noticed that they had a weird blurring going on. It was clear the lens had taken it's final shots. Luckily, I was with Marc Adamus on one of his tours. He offered to lend me his backup 5D and a 70-200. I was able to snag this picture. Not much to tell about the image. Just a simple, single shot. I just love the light and shadow play that goes on in sand dunes in the morning and evenings. I did notice something odd however, with the 5D. When you look at the image at 100%, there is a weird pattern overlay... almost looks like threading. Any 5D owners know about that?
